Delrin™ Acetal

Delrin™ a Dupont acetal resin, is a highly versatile engineering plastic with metal-like properties. It offers an excellent balance of desirable properties that bridge the gap between metals and ordinary plastics. The chemical composition and highly crystalline structure of Delrin™ acetal homopolymers offer a unique combination of physical properties not available with metals or most other plastics. Because of these properties, this material creates a wear surface, which is excellent for bearings, bushings and cams.

Stanyl™ Nylon 46

Stanyl™ TW341 is a nylon 46 resin used when a higher use temperature is required than nylon 66 can withstand for prolonged periods of time. Stanyl™ exhibits a melting temperature of 295 °C (560 °F) as well as higher crystalline structure compared to PA66. This feature give Stanyl™ a technical edge over other engineering plastics regard to heat resistance, mechanical properties at elevated temperatures, wear and friction behavior.

Zytel™ Nylon 66

This material possesses an outstanding balance of properties, combining strength, moderate stiffness, high service temperature and a high level of toughness. Because of its low coefficient of friction, resistance to repeated impact, and resistance to abrasion, it makes an excellent material for bushings, bearings and thrust washers

Minlon™ Mineral Reinforced Nylon

We use a toughened mineral reinforced nylon 66, which gives it superior impact strength as measured by both the Izod and Gardner (falling dart) impact tests. Adding our proprietary internal lubrication to this toughened resin provides the characteristics necessary for an extended wear bushing or spanner.
